Lava is molten rock, in order for rock to melt it needs to be from 600-1200 degrees celsius (that's 1100-2200 in fahrenheit if you're American). If the lava hasn't formed a flexible slightly solidified layer (which as the lava in the picture is completely red it hasn't) than even going close to it would be more than enough to kill you. Aka, the girl and father would be extra crispy and dead already and standing on a sofa would do absolutely nothing. Now where's my Buzz Killington award?

This comic is brought to in part by the powers of magic and imagination! Like snakes plated in dragon scales! (P.S. This snake is called a bush viper. Imagination says dragon snake. So much more interesting.)
